Complete the following steps:

1. Does the SRC that sent you here begin with 50B1 or 78D1?
   • No: Go to step step 3.
   • Yes: Continue with the next step.
2. Find the resource name that this error was logged against. The resource name can be obtained from the service action log (see Searching the service action log). Then, using the resource name, perform the following steps:
   1. Access SST or DST.
   2. Select Start a Service Tool.
   3. Select Hardware Service Manager.
   4. Select Locate resource by resource name.
   5. Enter the resource name that this error was logged against.
   6. Select the Associated packaging resources option for the expander.
   7. Select the Display detail for the expander/ESM option to display its location code.

   Replace the expander/ESM at the location displayed. For information on how to match location code to physical location and removal and replacement procedure, see Part locations and location codes.

   CCIN	Type and model	Part number	Description	Location code
   50B1	5887	See System parts.	Enclosure Services Manager (ESM)	Un-P1-C1, Un-P1-C2
   78D1	5147-024, ESLL, or ESLS	See System parts.	Enclosure Services Manager (ESM)	Un-P1-C1, Un-P1-C2

   This ends the procedure.
3. Is the device an internal device (not in an external expansion unit or a storage enclosure)?
   • No: Replace the expanders/ESMs in the external expansion unit or in the storage enclosure, one at a time until the problem is resolved. This ends the procedure.

     CCIN	Type and model	Part number	Description	Location code
     50B1	5887	See System parts.	Enclosure Services Manager (ESM)	Un-P1-C1, Un-P1-C2
     78D1	5147-024, ESLL, or ESLS	See System parts.	Enclosure Services Manager (ESM)	Un-P1-C1, Un-P1-C2

   • Yes: The expander is integrated into the device backplane.

     If you have not replaced the device backplane, replace it. Use the following table to determine the part number for the field replaceable unit (FRU). If you have already replaced the device backplane, continue with the next failing item in the failing item list. This ends the procedure.

     CCIN	Type and model	Part number	Description	Location code
     	5148-21L, 5148-22L, 8247-21L, 8247-22L, 8247-42L, 8284-21A, 8284-22A, 8286-41A, or 8286-42A	See System parts.	Drive backplane	Un-P2
